ATLAS COPCO - EPIROC COP 1840 HE REPLACEMENT PARTS

COP 1840 HE Parts Supply for Drifter Maintenance

For COP 1840 HE, the strongest parts request connects the operator’s service need with the workshop’s technical evidence. Where the equipment is used in drifter maintenance where the installed revision, component position and visible part references are critical to correct supply, wear discovered during inspection may expand the original list. A structured enquiry makes those additions easier to verify and price.

Parts Priority — COP 1840 HE

For this maintenance scenario, begin with bearings, then review front-head and service components and seal groups according to the actual repair scope. The order is intentionally model-specific: confirmed workshop findings should decide what is purchased rather than copying a standard list from another Atlas Copco / Epiroc machine.

Inspection Trigger

One condition worth investigating on COP 1840 HE is increasing bearing noise. Technicians should check bearing condition, lubrication quality, shaft support and surrounding clearances before the purchasing list is finalised. A symptom is useful evidence for inspection, but it should not be treated as proof that one particular component is the only cause.

Maintenance Coordination

For planned service, measure wear and clearance where practical instead of relying only on visual judgement. It is also useful to record operating hours and unusual symptoms before the planned shutdown. These steps give purchasing better identification data and help the workshop avoid discovering an unverified related item after the machine has already been opened.

Request Price and Availability

Send the COP 1840 HE part numbers you can confirm, quantities, available machine or serial information and destination country. Mark uncertain references clearly and include readable photos of markings or component position when identification is still required.

COP 1840 HE HYDRAULIC ROCK DRILL TECHNICAL REFERENCE

The Atlas Copco / Epiroc COP 1840 HE is evaluated as a hydraulic rock drill component group where impact energy, rotation torque, accumulator response and front head guidance must work together. The purpose of this page is not only to list replacement parts, but also to explain the technical relationships that help service teams identify wear items, overhaul components and hydraulic sealing parts more accurately.

Reference catalogue information for the COP 1840 family identifies a rock drill assembly with accumulator groups, return accumulator, hydraulic motor alternatives, seal kit, O-ring set, charging device and overhaul kit groups. The same engineering logic is useful when evaluating COP 1840 HE service requirements, but the final part selection should always be confirmed by the exact part number, drill configuration and machine information.

HYDRAULIC IMPACT SYSTEM

The impact section converts hydraulic pressure and flow into percussion energy. Piston movement, valve timing, cylinder sealing and guide alignment directly affect drilling energy transfer. If internal leakage increases or piston guidance becomes unstable, the drill may lose impact efficiency even when the external hydraulic supply appears normal.

Impact piston and piston guides control percussion movement.
Valve piston, valve seat and valve cone influence oil timing and pressure response.
Seal housings, seal rings and O-rings maintain internal pressure separation.
Damping components help reduce harmful vibration and shock transfer.

ACCUMULATOR AND PRESSURE STABILITY

Accumulator condition is critical in hydraulic rock drills because pressure fluctuation can reduce impact consistency and increase vibration. Diaphragms, test valves, charging connections, O-rings and return accumulator components should be checked as part of the complete pressure-stability system rather than as isolated spare parts.

A weak diaphragm, incorrect pre-charge, damaged O-ring or leaking test valve may cause unstable percussion, reduced drilling speed or repeated seal failure. For this reason, accumulator inspection is closely related to hydraulic oil cleanliness, seal condition and impact performance.

ROTATION DRIVE AND SHANK ADAPTER AREA

The rotation section transfers torque from the hydraulic motor through the gear housing, shaft, gear wheel, driver and rotation chuck toward the shank adapter. Wear in this area can create backlash, misalignment and abnormal vibration during top hammer drilling.

Hydraulic motor output affects rotation speed and torque transfer.
Gear housing, shaft and gear wheel support rotational load.
Roller bearings and needle bearings maintain alignment under impact load.
Rotation chuck, bushing and driver transmit torque to the drill steel connection.

FRONT HEAD, GUIDE AND FLUSHING FUNCTION

The front head area guides the drill steel and supports flushing flow. Cup seals, flushing head, guide components, stop rings and front part surfaces are exposed to abrasive water, rock dust and vibration. When the guide or seal surfaces wear, flushing performance may drop and contamination may enter sensitive internal areas.

Correct inspection of the front head should include guide wear, seal contact surfaces, flushing passages, shank adapter condition and visible leakage around the front section.

SEAL KIT, O-RING SET AND OVERHAUL COMPONENTS

Seal kits and O-ring sets should be evaluated with the full hydraulic circuit in mind. A seal kit does more than stop leakage; it protects pressure balance, reduces contamination entry and helps preserve impact energy. Overhaul kits normally combine sealing, bearing, fastener and wear components because several internal parts experience related service wear during high-impact operation.

Typical service items for the COP 1840 HE family may include seal kits, O-rings, radial lip seals, cup seals, seal washers, bushings, piston guides, bearings, shims, circlips, side bolts, driver parts and damping components. Final compatibility must be verified before ordering.

COMMON FAILURE SYMPTOMS AND POSSIBLE CAUSES

Service Symptom	Possible Technical Cause	Related Component Area

PART IDENTIFICATION FOR COP 1840 HE

Correct identification should be based on the hydraulic rock drill model, part number, component group and machine configuration. Similar Atlas Copco / Epiroc rock drills may share engineering concepts while using different seal dimensions, hydraulic motor options, guide components or overhaul kits. For accurate quotation, Vomeks can check the part number, component description, photos and available machine information before supply.
